Abstract
Procedure for the preparation of derivatives of 3-benzylidenhydrazino-6-aminopyridazine, of the formula **(See formula)** in which R represents methyl, ethyl, propyl, hydroxyethyl or 2-hydroxypropyl, that constitute intermediate compounds in the synthesis of pharmacologically active substances, characterized in that a thiopyridazine of the formula is reacted **(See formula)** in which X represents Cl, Br or S-CH3 with an amino alcohol of the formula **(See formula)** and by which the thus obtained substituted dialkylamino thiomethylpyridazine is reacted with hydrazine, preferably in the presence of an aprotic solvent, and is then treated with benzaldehyde to obtain the desired compounds.
